Lucifer

An object that has no will of its own, capable, if need be, of opposing its creator, and with no qualities other than its creator’s, such an object has no independent existence and is incapable of ethical decision…. Therefore Lucifer was perhaps the one who best understood the divine will struggling to create a world and who carried out that will most faithfully. For, by rebelling against God, he became the active principle of a creation which opposed to God a counter-will of its own.
